- * --------------------------------------------------------------------------------------------------------------------
- * Example sketch/program to test your firmware.
- * --------------------------------------------------------------------------------------------------------------------
- * This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid
- *
- * This example test the firmware of your MFRC522 reader module, only known version can be checked. If the test passed
- * it do not mean that your module is faultless! Some modules have bad or broken antennas or the PICC is broken.
- * NOTE: for more informations read the README.rst

- * @author Rotzbua
- * @license Released into the public domain.
